SPECIFICATION forming part of Letters Patent No. 366,315, dated July 12,1887.

Application filed November 9, 1886 Serial No. 218,423. (No model.)

To all whom it may concern:

Be it known that we, ANDREW JACKSON HAWKINS and J OHNNVALKER WILKINs,citizens of the United States, residing at Dallas, in the county ofDallas and State of Texas, have invented a new and useful Improvement inCombination. Axle and Oil-Box for Railways, Street-Oars, and otherMachinery, of which the following is a specification.

Ourinvention relates to an improvement in ear-axles and bearing-boxestherefor; and it consists in the peculiar construction and combinationof devices, that will be more fully set forth hereinafter, andparticularly pointed out in the claims.

In the drawings, Figure l is an elevation of a portion of a caraxle, thebearing-box being shown in transverse section. Fig. 2 is a verticalsectional view taken on the line mm of Fig. 1. Fig. 3 is a perspectiveview of the bearing-box.

A represents the car-axle, the outer end of which, beyond the outer sideof the wheel B, is enlarged to form an annular collar, 0. A suitablespace is left between the inner side of the said collar and the opposingouter side of the wheel. The collar is provided with a peripheralannular groove, D, thereby forming flanges E on the'sides of the saidgroove.

F represents the bearing-box, comprising the upper section, G, and thelower section, H. The said sections are secured together by means ofbolts I and metallic straps K, which are fitted in'grooves that are madeon the upper and lower sides of the box. Between the opposing edges ofthe sections G and H, on

one side thereof, is made a circular opening, L, the diameter of whichexceeds the diameter of that portion of the axle between the collar 0and the wheel. In the upper side of the upper section of the box is madea recess, M, to receive the block N, the under side of which is concaveand bears upon the upper side of the groove 13 of the annular collar. Inthe outer side of the box is made an opening, 0, through which oil maybe supplied to the box. Enough oil ispoured into the box to partlysubmerge the lower side of the annular collar of the axle, so that asthe axle rotates the oil will be taken up by the annular collar, andthus the oil will become diffused over the face of the collar and thebearing-face of the block N, so as to thoroughly lubricate the axle andprevent the same from becoming heated.

As the opening L through which the axle enters the box is larger thanthe axle, it follows that there is no friction between the axle and thesides of the box, the only friction being between the collar 0 and thebearingblock N.

The collar 0 is preferably made separately from the axle, and is shrunkon the end of the same. By this construction the collar may be removedfrom the axle and replaced by a new one after it has become worn, andthe bearingbloclc N may also be renewed from time to time, thuspreventing wear on the axle and adding greatly to the durability both ofthe axle and of the bearing-box.

Having thus described our invention, we clain1- V i 1. The car axle boxcomprising the separable upper and lower sections having the 1011-gitudinal grooves on their respective upper and lower sides, the strapsK, fitting in the said groove, and the bolts I, engaging the said strapsand clamping the sections of the box together, substantially asdescribed.

2. The combination of the box comprising the separable upper and lowersections, and having the opening L in one side, formed in the opposingedges of the separable sections, with the axle extending through thesaid opening, and the block N, bearing on the said axle and located inthe box, substantially as de scribed- 3. The box composing the separablesections, in combination with the axle having its end fitting within thebox, the collar shrunk onto the end of the axle within the box, saidcollar having the annular flanges, and the block pressing on the coll-ar within the flanges, as set forth.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
